The Illinois DNR states, "The Project restored 150 acres of eroded quarry with chronic flooding and 20-foot tall degraded slopes into a recreational park amenity. Over 86 acres of the Project Site now retain and infiltrate runoff from the sub-watershed through the 100-year, 24-hour rainfall recurrence interval. The stormwater management and biodiversity project both encourages natural landscapes and helps greatly reduce the deposition of sediment into Jelkes Creek. The Project should become a model project for future quarry restoration efforts."
